Hi all, (A:Kohlsman setting hg, inHG) (A:SEA LEVEL PRESSURE, inHG) == Can't get this equal because they both give too many decimal places. How can you reduce it to give only two places.

You could try (value) 100 * int 100 / Tom

Subtract one value from the other. Make the difference absolute and check it against 0.005Doug

Thanks again guys Another maths lesson and a working code. Paul
